Application January 22, 1947, Serial Nit-"223,626"

This 'invention' "relates to an automatic dispensing shaving brush that is adapted to dispense liquid shaving soap from the reservoir in the handle into the bristles by means of a single operation. a

An object of the invention is to provide a dispensingshaving brush constructed of a few simple parts, that is easy to operate, durable and efiihem in use, and can be inexpensively manufacfined :for the purpose designed.

With the above and other objects in view, the invention consists of the novel details of construction, arrangement and combination of parts more {fully hereinafter described, claimed and illustrated in the accompanying drawing inwhich:

Figure 1 is a vertical sectional view of an embodiment of the invention;

Figure 2 is a sectional view on the line 22 of Figure 1;

Figure 3 is an enlarged detailed fragmentary sectional view of the sealing end of the plunger;

Figure 4 is a sectional view on the line 4--4 of Figure 3;

Figure 5 is a detailed fragmentary view partly in section of the plunger end having the seal removed therefrom;

Figure 6 is a side elevational view of'the seal;

Figure 7 is a bottom plan view thereof;

Figure 8 is an elevational view of the screw p;

Figure 9 is a top plan view thereof and Figure 10 is an elevational view of a rubber disc adapted to be placed in the screw top.

Referring more in detail to the drawing, the I reference numeral designates the shaving brush which comprises the cylindrical handle 2| having an annular concave groove 22 formed in its outer periphery to accommodate the fingers of the user to provide a firm non-slipping grip on the handle.

The handle, at the top thereof, is provided with a centrally located internally threaded opening 23, and this opening communicates with a circular reservoir 24 in the upper part of the handle above the groove 22, which is adapted to hold liquid shaving soap.

Depending below the reservoir 24 from the center thereof, is the reduced circular bore 25, which extends for the greater portion of the remainder of the handle, and the lower end of the bore is closed by a partition 26, having the centrally located bore 21, and the bottom of the bore flares outwardly to provide the truncated conical seat 28, the purpose of which will be later described.

Surrounding the bore 25, at the lower end ofthe handle 2|, is a circular recess 29 which is connected with the bore 25, and has inner and outer walls 30 and 3| between which the bristles 1 Claim. (01. 22 2;4 5: 10)" 2 Marc :positioned and retained-therein in any suitable manner.

Acap 3310f the same diameter as the handle 21 is provided with. a. centrally located reduced externally threaded portion 34 which' dsiadapted to be threadably received in the internally threaded opening 23 in the handle to close the upper end thereof.

The cap 33 is .provided with the centrally located bore 35 which is adapted to slida-blyzreceive the plunger rod 33 having the plunger 31 on the lower end thereof, and the disc shaped top 38 on the upperend thereof isof a size to pass through the bore 35. p

The top 33 of theplunger rod is received in the circular recess 39 which is connected with and communicates with the bore 35. Concentric with the recess 39 and communicating therewith is a groove 40 which is adapted to retain the rubber disc 4| therein, and an opening 42 in the upper surface of the top 33 permits access to the rubber disc 4| for a purpose to be later described.

At the junction of the reservoir 24 and bore 25 thus is formed a shoulder 43 upon which is adapted to rest, the upwardly curved ends 44 of a flat curved spring 45, which passes through the rod 36, and is fixed thereto. This spring forces the rod upwardly against the disc 4|, as shown in Figure 1.

The plunger 31 is provided with vertical bores 46 which are in diametricallyv opposed relation to each other on opposite sides of the rod 36. The bores 46 are provided with centrally located outlet ports 41 which are closed by circular shaped flap valves 48 which are secured to the lower surface of the plunger 31.

Depending from the center of the lower surface of the plunger 31 is the circular projection 49 which is provided with a centrally located internally threaded bore 50, which is adapted to receive the externally threaded stem 5| of the truncated conical seal 52, which is adapted to be received in the seat 28 of the bore 21.

To operate the invention, the cap 33 is removed and the reservoir 24 and bore 25 are filled with liquid soap.

I With the plunger in the position shown in Figure 1, the liquid will pass through the flap valves 48 below the plunger 31; then the cap is replaced and the brush is ready for operation. Seal 52 prevents the liquid from leaving the handle until pressure is applied to the disc 4|, causing the rod 36 and plunger 3! to move downwardly within the handle, causing the flap valves 48 to close, and moving the seal 52 from its seat 28. The pressure now exerted by the plunger will force the liquid soap past the seal 52 into the bristles. Upon release of pressure on disc 4|, the spring it forces the rod 33 upwardly to normal position, seating the seal 52, and open-,-

ing the valves 48, to permit the soap to again pass through the valves. If enough soap is not obtained by the first operation, the action previouslyexplained is repeated. Upon release of pressure on the disc M, the handle is sealed to prevent any soap from entering the bristles until a:

pressure is again applied to the disc 4!.

Thus an eificient and easily operated dispens ing shaving brush is provided, and it is believed that from the foregoing description, the operation and construction of the invention will be apparent to those skilled in the; art.

It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within thespirit-of the invention and the scope of the appended claim. u 'Having thus described the invention, what is claimed as new and-desired to be secured by Let- An' automatic dispensing means for shaving brusheshaving a handle, a reservoir in said handle at the upper end thereof, a centrally located bore in the lower end of the handle communicating with said reservoir, and a partition closing the lower end of the bore having a cen- "trally' located bore therein, comprising a truncated conical shaped seat in the lower surface of the partition communicating with the bore in said-partition, a plungenmovably mounted in the handle, sealing means on the bottom of the plunger adapted to engage the seat in the partition, a rod on said plunger extending upwardly through said handle, a fiatcurved spring' carried by said rod which resting at its opposite ends on the bottom of the reservoir is adapted to force said rod upwardly to seat said sealing means, a rubber disc in the top of the handle adapted to engage the upper end of and move said rod downwardly when pressure is applied thereto, diametrically opposed bores in said plunger and flap valves suitably mounted on the bottom of said plunger that are adapted to close said bores when said plunger is moved downwardly.
